More Than Half of Mobile Apps Not Secure, Report Says - 5 views

  •  
    An article about the unsafe nature of many mobile phone applications including commerce and finance related apps. This article allows the reader to see the increasing problem of security holes of these apps and sites like Twitter who were hit with the same problems, such as "cross site scripting."

    Security in this day an age has become a major problem. The protection of hardware, software, machines, and networks from unauthorized access is becoming increasingly harder because hackers have gotten smarter in identifying the security holes of these programs. Mobile phone applications are just one of their latest hits. More than half of the applications on mobile phones are considered unsafe and therefore vulnerable to security attacks. Third party codes were even more devastating with a "81 percent failure rate." Commerce and finance related apps did just as poorly, both exceeding just about the half way mark. The process of fixing these security holes has become quicker over, however, not quick enough. It takes sixteen days on average to fix the problems and this is rather long time in a society that can get and bit of information in the palms of their hands in nano seconds. Hackers are also going into other user's profiles, or creating fake profiles in order to spread "cross site scripting." This was recently seen as a problem for Twitter and it's users. Tweets were changed into different colors, and there were unwelcomed pop-ups that would appear to users when they clicked on a Tweet. This would then publish the original script on that user's page without their knowledge, or consent. This is a problem that has taken over mobile apps, resulting in "51 percent of all vulnerabilities." The stakeholders of this issue are mainly the users. However, it is also a problem for the companies who created the application and those who are fixing it when it goes down, if not the creator. In the world of applications on mobile phones, things are expanding quickly and largely. However, with this great expansion, there are downsides when more than half are deemed not secure. Although there are various apps that are safe, our need to have everything in our sight available to us, even the most seemingly useless app, has driven us to put our devices, privacy,security, and

    In a way, downloading an app or downloading anything in fact is like interviewing a book or finding a reliable source. It's always better to pick from an author or publisher you know about. Usually, more well known companies will release an app and if there are a lot of people complaining about it, then they will fix it. It takes patience and control to wait for a better version to come out so that you know its safe. Additionally, people should take more caution into the apps they are using and what kind of information they are registering in it.

Usage of weak encryption codes in RFIDs - 0 views

  •  
    In big corporations such as Wal-Mart, the use of RFIDs has increased, but the disadvantages of RFID is now a serious issue. With the use of RFIDs on items, the customer is able to avoid waiting at a register, and the RFID will charge the person's credit-card. Yet the tags embedded in the items bought, such as clothing, can be tracked down by the store management systems, risking customers' security and privacy. Since RFIDs do not require a power supply or batteries to operate, all that is needed is a wireless scanner, which Wal-Mart's managing system uses to keep track of the items. Privacy has now become a major issue within the use of RFIDs for many Wal-Mart customers. Also, in many credit cards and "gas-cards", RFIDs are being used, yet the information on the tags also stays within the system. At airports, many modern passports are now using RFID tags that can be scanned from a range as far as 30 feet. Thus this results in chaos for the passengers, and an issue in being able to control the airport security properly.
  •  
    Large scale businesses like Wal-mart and government authorities in passport make use of sophisticated RFIDs which make the data stored in them or to be accesses through them safe, which helps them keep their business data or data of the clients(in some cases passport holders) safe, however many corporates make use of cheap RFIDs which have a weak encryption code to protect them. This code can be broken easily and hence the client of that RFID is vulnerable to hackers. Ford for example makes use of RFIDs manufactured by Texas Instruments, in their car keys. These RFIDs are protected by very weak codes, hence it is easy for thieves to break the code and steal cars.

Electronic health records raise doubt - The Boston Globe - 11 views

  •  
    "Google Health and others in the fast-growing personal health record business say they are offering a revolutionary tool to help patients navigate a fragmented healthcare system, but some doctors fear that inaccurate information from billing data could lead to improper treatment."

    This article provides a possible service that can be used in the east African country our case study is on. Google health is a free service that would give all patients the opportunity to store their health records digitially, making it easier for doctors to access it. Especially if telemedicine were to be used, having electronic health records would be a great benefit. However, the issue of reliability is especially troubling when it comes to using services like Google health in this context. There have been many reported errors with the diagnoses of patients using this service, and it is crucial that the records are checked by both patients and doctors to ensure that all information listed is correct. Literacy rates are much lower in rural African settings, creating a problem for patients who may be unaware of inaccurate information on their records. Especially for individuals in critical conditions, fatal mistakes can therefore be made.
  •  
    Electronic Health Records are also used in the case study. Patients and doctors rely on these records for accurate data, but it is rather difficult, due to the lack of reliability with which Google Health updates patient's health data. In order for Dr. Ogola's plan to work (face the challenges, create a modern health system), he must implement such health records that will store patients' information on an accessible, secure and easy to use database. This would help patients, doctors and nurses share data without having to travel long distances. Data would be secure and also accessible to the three parties. However, this would require a reliable system (more than Google Health) so as to not provide inaccurate data to the patients. Patient involvement in the care of his/her own data would be required for an such an erroneous system, as would a reliable source of healthcare information on the patients. Unreliable sources can potentially damage the whole system.
  •  
    The use of Electronic Health Records in this article can be applied to our case study. Firstly, it would make the transfer of patient data easier and faster, this would increase the quality of care that the hospitals and clinics offer to their patients. These Electronic Health Records can also keep data from different doctors in order, for example if a patient visits several Doctors all of their information will be in one place and ready to access when ever necessary. In the case study if doctors had a more accurate picture of the patients medical history they would be more prepared to make diagnoses, especially when they are working with strange cases. This would also help to increase the quality of treatment that the patient would receive. Digital Health Records are easy to update both the patient and the doctor can edit the Electronic Health Record, it also can keep track of test results, and medications that the patient is currently using. Electronic Health Records allow patients to be more active in their health care allowing them to see and have access to all of their medical information. Even though this IT system is ideal for our case study there are some things we should take into consideration. In our case study we would have to make sure that equality of access is equal for everyone, there may be some people living on the outskirts of villages that might not have access to Digital Health Records. We would also have to assume that everyone would know how to use the Digital Health Record. Meaning how to update it and how to look for errors. Lastly we would have to assume that the patient would make good use out of having an Electronic Health Record. They would have to constantly be updating and checking their records to see if there is any missing information or any errors within their data. Lastly, the coding system would have to be revised, it is confusing and very inaccurate, there should be a new coding system that makes understanding your own records

    In this article, the use of electronic health records is discussed. However, some problems arising from their use are also introduced, including inaccurate patient information. In the world of the case study, this IT system, electronic health records. is quite relevant and can be useful. EHRs can be used in Africa to connect rural doctors to hospitals and other professional health care workers in better facilities. This way patients' records can be reviewed, diagnoses can be made and other help can be given. However, if this system is taken advantage of in Africa, its users must be certain that the information in the records is accurate and comes from a reliable source. This is because if the information in a record is inaccurate, incorrect diagnosis and/or medication can be given as was the situation in the article. These kinds of mistakes can be detrimental to some patients.

    This article elaborates on the drawbacks of electronic health files. Although the IT System, Google Health, seems that it will make getting quality health care much easier and quicker, there is a major issue of possible inaccurate information. These inaccuracies or exaggerated diagnoses on Google Health may prevent patients from receiving the care they need, and Google Earth is prone to human error as real people are responsible for inputting insurance billing codes or mislabeling a lab test with a disease that is hoped to be ruled out. This has an impact on our African case study as this article illustrates one of the highly potential problems that arise from the use of telemedicine. Although medical centers in Africa would be able to eliminate the tedious process of paper work by instantly communicating records over the internet, these records can be inaccurate and therefore compromise an already sick patients health even further. However, for the case study, EMR's prove to be a very feasible solution for the lack of communication and distances between villages and health centers, but a solution must be made in order to counteract the potential misdiagnoses'. One solution could be that patients would check their EMR's for accuracy, but with the poor conditions of living in the African villages and poor or no internet service, this solution does not seem possible for the case study.

    This article is about a man getting his health information in an electronic health records massed up. There's an issue with the EMRs in the sense that they are sometimes unreliable. In regard to the Case study, as they want to place EMRs into their hospitals and clinics they ma have this issue with reliability. But it has shown signs of improvement from paper records. But the hospitals and clinics in the East African cities will need to hire more staff to make sure these records are up to date and accurate. As for the health of the patients, EMRs has its benefits and drawbacks. If the information is accurate then a life could be saved and that person could be properly cared for in a more timely fashion, but if the information isn't accurate they could be given unneeded surgery or given the wrong drugs. The EMRs could help the efficiency of the hospitals and clinics because they could work faster and get to more patients without wasting countless time looking through paper records.

    This article arises a social and ethical issue of integrity of electronic health records. In this article, Dave deBronkart faced this issue when he transferred his medical records to Google Health. His information was inaccurately transferred because of the incorrect coding that insurance companies use. The database then used this incorrect coding and stated that Dave had other health problems, which he never had. The lack of codes makes the database more likely to make an inaccurate diagnosis. It also suffers from reliability because if the information, doctors can't rely on it to make correct diagnosis. Electronic databases are very useful and can be used in Oobunta if its integrity is improved. It will allow patients in villages that can't afford travel to share their symptoms and past medical history with doctors in the hospital. This will cut costs for both doctors and patients because they won't have to pay for transportation. It will also benefit the patients because it will let them be diagnosed accurately especially if they don't have enough resources or medical care in their village.

    This article covers a recent problem that has risen from the use of Electronic Medical Records. Google's new Google Health, a service that gathers e-health records for patients all in one place has become unreliable. Google Health gathers medical information from billing records, which is an inaccurate source of information. The medical records on the site also do not distinguish between recent illnesses and past illnesses, and does not indicate the level of severity for the health issues. The diagnostic medical coding is to blame for inaccuracies in information gleaned from insurance data, mostly because it is clunky and includes tests for diseases that doctors hope to rule out, not for diseases that the patients necessarily have. The problems that the unwieldy code and medical records in Google Health bring up are enormous. Information is inaccurate and out of date, and this is potentially deadly when patients are being treated. The issue of reliability is that data in the records is out of date, and entered incorrectly, which could be the difference between life and death for patients with dangerous diseases.

    This article was about electronic medical records. They allow patients to share their health information with doctors over the Internet, using Goggle Health. However, this application is not completely accurate. It takes information from insurance bills. These insurance bills may not be precise in describing the treatment of a patient because of their lack of codes. This raises the issue of reliability of the electronic health records. Inaccurate records could stop a doctor from performing a life saving procedure on a patient. The article relates to the case study because it talks about the drawbacks of having electronic medical records. In order for issues with reliability and integrity to be avoided in Oobunta, patients should regularly check their records to ensure their accuracy. Doctors and patients should also communicate more to eliminate problems within the health records.

    In this article, a new electronic health system arose. In order for one to use this newly aged system, their personal health records must be transferred. According to the article, "accuracy gets lost in translation" (Wangsness). Due to the fact that certain information is getting lost in translation, many issues have been brought up, such as reliability. Health records are vital for every individual because they contain information that cannot be found anywhere else. A loss in data, such as certain dates, can lead to many problems for the patients during treatment. As a solution, people are asked to do one thing. They are told to check out their record and see if everything is accurate. There is a positive side for this new system and it relates directly to our case study. These Google health records are easily transferable. If one needs to send out their information to a hospital for a diagnosis, they can do so in no time. In the case study, people in Africa are having trouble getting to a hospital because of the expenses and lack of transportation. By using these Google electronic health records, the people would be able to e-mail their record to a hospital for a direct prognoses. This would save them so much money and time because they would be able to complete this task in the comfort of their own home, or anyplace with internet access. These electronic health records can solve many problems in Africa.

    This case study tackles the issues of Integrity and Reliability. The article talks about inaccurate health records and it effect on patients who want to follow updates on their health status. The stakeholders in this articles are patients because they are the ones who need accurate information, doctors because patients come to them when they read inaccurate information about their health and the people who control the information in the databases because they are the ones responsible for whether or not the information is accurate. Integrity is an appropriate Social and Ethical Issue because the information in the databases have a been changed accidentally, in turn affecting accuracy. Reliability is even better because is directly about accuracy of data, if it is entered incorrectly. If data is entered wrong patients lose trust in them. This is especially relevant to databases which is the major IT system discussed in this article. In relation to the case study it is important to find a solution for the patients of Africa, that is as efficient as possible. In a place like the one described in the study it is important to save time by being as accurate as possible and making sure that patents and doctors can understand the information on databases, ensuring more successful treatments for the patients.
  •  
    In the East African city, the medical facilities all contain databases that their patient's health records are recorded on, however the platform for each database varies between each clinic and the main hospital. This in turn makes it more difficult to exchange health records between each clinic and the main hospital.This article brings up a solution to the health records exchange problem that are within this East African Region. Google Health is a database that is in the cloud and makes it possible to exchange health records through the internet. This form of exchanging data for a patient helps to keep a patient's data up to date. Now though this could be a great solution it comes with many drawbacks from the system and the lacking materials from the East African region makes it difficulty to better utilize it.

In Haiti, Practicing Medicine From Afar - 0 views

  •  
    (NOT FINISHED) After the devastation of Haiti's earthquake, impoverishment plagued the millions of patients, in dire need for medical assistance and resources. The "low tech" equipment failed to meet the needs of the population, so tele medicine is being adapted.
  •  
    Medical facilities in Haiti are in essence trying to integrate satellite connection and internet service (along with increased bandwidth) in order to greatly expand the distribution and administering of medical services. Donated by the other organizations in Miami, the Haitian hospitals are now given the opportunity to form intercommunication via a wireless regional network system (internet service provided by neighboring countries, such as the Dominican Republic). One of the primary stakeholders, the patient and injured Haitian individuals required to maintain necessary medical help from the American doctors and medical professionals (other primary stakeholder). Such IT systems, enable the patients suffering from the devastating results of the earthquake to retrieve an increased amount of help and attention from doctors and other medical health professionals in other parts of the world, specifically recruiting medical help centralized in the United States. The adapted procedures of tele health already in American hospitals, including the use of internet messaging, x rays, scans, and medical reports all enable doctors to obtain confrontation and collaboration with Haitian patients on accurate and more reliable grounds. The scenario included in the article is Health, and the main theme is"medical information administration and marketing sales" for this pertains to telemedicine as a branched off aspect. In regards to the social and ethical considerations, the issue of the digital divide and equality of access is greatly highlighted in the article; telemedicine linked medical services found in another nation, to the needy Haitian population thus diminishing global boundaries placed up by the differences in development and advancement in certain regions of the globe. The digital divide that took control over Haitian lives( due to the catastrophic events of the earthquake) eliminated sources of internet connection, hardware and available software equipment to run teleme
